I was using the ‘air to water interface’ as a similar example of solving for a non-lens distortion with typical radial lens distortion parameters like Brown et al. In case you’re interested, I was referring to the refraction index of glass and water in underwater photography being solved – imperfectly – as a ‘lens’ by the solver.
I bring it up because the penalty in both cases (underwater and corrected photos) is that many SIFT points won’t satisfy epipolar geometry constraints and the resulting reconstruction is necessarily diminished.
That is, if RC can’t understand the lens correction applied before, many good matching points will be discarded by the ‘double-fitting’ of the camera model.
That will be true with any of the supported models, as they have ground truth idealized camera models from EXIF but can’t undo the distortion present when applying their camera model – thus, ‘double-fitting’.
